Specific embodiment

In the drawings, essentially similar part carries identical reference.

Fig. 1 is shown schematically for heating, ventilation and/or the air-conditioning unit 1 of motor vehicle interiors.

The unit includes the air intake casing 3 for being connected to spiral case 5, and spiral case 5 accommodates wheel, also referred to as blower fan (not shown). Then the spiral case 5 is fluidly connected to annealing device 6.

Air intake casing 3 can form two different parts with spiral case 5, and such as in this example, or formation is connected to heat treatment The single part of device 6.

Fig. 2 shows air intake casing 3 in greater detail.

Air intake casing 3 is equipped with outside air inlet 7, and which allows the extraneous air stream 9 outside vehicle interior to be permitted Perhaps into the inside of housing 1.

Housing 3 is also equipped with recirculation air entrance 11, and which allows the recirculation air flow 13 from vehicle interior to enter The inside of housing 3.

Being put into operation by will be received in the wheel in spiral case 5, causing the air stream of the type to enter (either extraneous air 9 and/or recirculation air 13).

Air stream 15 is the air stream from air intake casing 3, the air stream by via air outlet slit 17 towards inside spiral case 5 Guiding, advances then towards annealing device.

Between the air outlet slit 17 and its outside air inlet 7 and recirculation air entrance 11 of air intake casing 3, lobe is pivoted Piece 19 can be between the first extreme position of closure recirculation air entrance 11 and the second extreme position for closing outer air intake 7 It is mobile.

When in the first extreme position of the movable limb 19 in its closure recirculation air entrance 11, ventilation, heating and/ Or air-conditioning unit is then in extraneous air supply model.

When movable limb 19 in its closure outside air inlet 7 the second extreme position in when, ventilation, heating and/or Air-conditioning unit is then in recirculation air supply model.

Between the two extreme positions, movable limb 19 can take centre position (as shown in Figure 2), it is ensured that while both will Extraneous air stream 9 introduces recirculation air flow 13 inside air intake casing 3 again.

And, in fig. 2, air intake casing 3 includes the radiator 20 relative with outside air inlet 7, and which is allowed by driving The heat that the motor of wheel and control electronics are produced is dissipated.

Now with reference to Fig. 3 to 6, which shows movable pivot limb 19 in greater detail.

Drum-type movably pivots limb 19 includes recessed wall 21, for deflecting air streams, the wall and two side walls 23 and 25 Side connects (flanked).Limb 19 further has two pivot journals 32 and 34, and one of them is for example connected to fair Perhaps the motorized actuation mechanism that limb 19 is placed in desired locations.

On the either side of two pivot journals 32 and 34, limb 19 includes circular edge 26 and 28, and each is Horse hoof Shape, with the open end being oriented to towards pivot journals 32 and 34.Each circular edge is provided with packing ring 30, described above Two extreme positions, packing ring 30 contacted with the wall of air intake casing 3.

Limb 19 further includes lateral deflection device 27, for example, be embodied as the shape of the vertical straight wall for rising on recessed wall 21 Formula, such as substantially along the direction of pivot journals 32 and 34, and extend between two side walls 23 and 25.

When limb 19 is in partial recirculation position, at least two whirlpools are formed in the volume limited by limb 19 At the edge 26 and 28 of the limb 19 in portion, side is 9 whirlpool of extraneous air stream, and side is 13 whirlpool of recirculation air flow.

Deflector 27 causes for the two whirlpools being consequently formed to be separated into possibility, and avoids mutual between them Effect, and avoid result in and produce the vibration of noise of flapping, this flap noise in the case of the limb of prior art in part again It has been detected in circulation position.

Deflector 27 therefore ensures that extraneous air and recirculation air towards the more preferable guiding of wheel.

Have been observed that the noise of 5dB to 25dB is reduced in the frequency band of 30 to 160Hz, without causing the attached of air stream Plus-pressure loses.

As shown in Figure 5, deflector 27 is symmetrically arranged at the bottom of limb 19, in other words, by the spill of limb 19 27 points of the internal volume deflector that shape is limited is two equal volumes, but when deflector 27 with regard to wall 21 for laterally simultaneously And when there is certain degree of deflection parallel to pivot axis, it is contemplated that other positions.

Deflector 27 is preferably implemented as and movably pivots 19 one of limb, and is injection molded into single-piece.

For the ease of removing from mould, in manufacturing process, the wall of deflector 27 and the stripping direction direction of limb is formed Alignment.

Deflector is with the height h for starting at least 26mm from bottom.

Further, deflector 27 also includes central recess 31, and which can equally be described as recess.The recess has Trapezoidal shape, little base portion relative to limb 21 recessed portion near.

When limb 19 is in partial recirculation position, the central recess 31 allows the fresh air towards radiator 20 Stream increases.

Hypothesis is more effectively cooled down and is realized by radiator 20 due to central recess 31 so that by the motor and electricity of driving wheel The heat that sub- control device is produced is dissipated, then therefore the radiator 20 can have less size, in terms of cost and size Produce benefit.

Central recess 31 is with about 5 to 8mm depth (trapezoidal height), such as 6mm, and for trapezoidal big base The width of the about 33mm in portion, and the width of the 20mm for trapezoidal little base portion.

It is conceivable that other embodiment is made without departing from the scope of the present invention.

Therefore, deflector 27 can also have concave shape.

Which can be addition part, for example, be attached to the inside of limb.

It is therefore clear that deflector 27 causes the noise of the partially opening of the limb 19/make position in air intake casing 3 Generation is efficiently solved.
